One bed device 50 among the plurality of bed devices 50 includes abed 51 and the user interface device 55. The user interface device 55 isconnected to the bed 51.

The plurality of user interface devices 55 include user interfacedevices 55A to 55C and so on, for example. The user interface devices55A to 55C respectively output user interface device information 55 iAto 55 iC and so on. The plurality of user interface device information55 i (the user interface device information 55 iA to 55 iC and so on) issupplied to the acquisition unit 61I via a server 65 or the like, forexample. The number of user interface devices constituting the pluralityof user interface devices 55 is a desired integer no smaller than 2. Thenumber of sets of user interface device information constituting theplurality of user interface device information 55 i corresponds to thenumber of user interface devices constituting the plurality of userinterface devices 55.

The acquisition unit 61I is a communication circuit, for example. Theacquisition unit 61I includes an electric circuit, for example. Theacquisition unit 61I and the plurality of user interface devices 55exchange information (signals) by a wired or wireless method selected asdesired.

The plurality of user interface device information 55 i acquired fromthe plurality of user interface devices 55 may be supplied to anelectronic medical record storage unit 66 or the like via the server 65,for example.

The plurality of user interface devices 55 (the user interface devices55A to 55C and so on) are provided to correspond respectively to theplurality of beds 51 (beds 51A to 51C and so on).

The bed 51 includes a moving part 70, for example. The moving part 70includes a back section 70 a, a knee section 70 b, a leg section 70 c, aheight modifying part 70 d (a bed elevator, for example), and so on, forexample. By operating the moving part 70, at least one of“back-raising”, “knee-raising”, “height adjustment”, and “inclining” canbe performed. “Inclining” includes at least one of rolling and tilting.

An actuator or the like, for example, moves the moving part 70. Themoving part 70 may include a sensor (a load sensor, for example), forexample. Information relating to the state of a user of the bed 51 maybe acquired by detecting a load exerted on the actuator. The user is apatient, a care receiver, or the like, for example. For example, theload sensor or the like provided on the moving part 70 may outputinformation relating to the user (at least one of sitting up, sitting onthe edge of the bed, bed departure, and “monitoring”, for example).“Monitoring” is a state in which the user remains out of bedcontinuously for a specified time, for example. When the user remainsout of bed continuously for the specified time, the load sensor or thelike outputs a signal (information) relating to “monitoring”.

Bed moving part information 51 i is supplied to the user interfacedevice 55 from each of (one of) the plurality of beds 51. The bed movingpart information 51 i includes information relating to at least one ofthe height and the angle of one of the plurality of beds. The bed movingpart information 51 i includes whether or not the height of the bed 51is at a minimum, for example. The bed moving part information 51 iincludes information relating to the angle of at least one of the backsection 70 a, the knee section 70 b, and the leg section 70 c, forexample. The bed moving part information 51 i may also includeinformation relating to the angle of incline of the bed 51.

In this example, the bed 51 is provided with an auxiliary device 52. Theauxiliary device 52 is a sheet (or a plate), for example. The auxiliarydevice 52 is provided between the section of the bed 51 and themattress, for example. The auxiliary device 52 includes a sensor (atleast one of a vibration sensor, a noise sensor, and a force sensor, orthe like), for example. The vibration sensor includes an air pressuresensor (a pressure sensor, for example). The auxiliary device 52 iscapable of detecting at least one of sleeping, waking up, sitting up,bed departure, monitoring, heart rate, and respiration rate in relationto the user, for example. The detection result is supplied to one of theplurality of user interface devices 55. For example, the sensor includedin the auxiliary device 52 detects the user behavior state of the user.The user behavior state includes at least one of bed departure,sleeping, waking up (lying flat in bed), sitting up, and sitting on theedge of the bed in relation to the user of the bed 51. User behaviorinformation 52 i including information relating to the user behaviorstate is supplied to the plurality of user interface devices 55.

The bed 51 may acquire at least a part of the user behavior information52 i. When a sensor is provided in the actuator provided on the bed 51,as described above, the bed 51 may detect the user behavior state (astate including at least one of bed departure, sleeping, waking up,sitting up, and sitting on the edge of the bed). The bed 51 may beconsidered to include the auxiliary device 52.

In this example, measurement information 53 i is also supplied to theuser interface device 55. A measurement device 53 acquires themeasurement information 53 i. The measurement device 53 includes atleast one of a blood pressure gauge 53 a, a pulse oximeter 53 b, athermometer 53 c, and a blood glucose meter 53 d, for example. Themeasurement device 53 acquires information (vital signs information, forexample) relating to at least one of the blood pressure, the bloodoxygen saturation (SpO₂), the blood glucose level, and the bodytemperature of the user, for example. The blood oxygen saturation is thepercutaneous arterial oxygen saturation, for example. The measurementdevice 53 supplies the vital signs information to the user interfacedevice 55 by communicating with the user interface device 55, forexample. This communication is performed by short-range wirelesscommunication, for example. A nurse or the like may input at least apart of the vital signs information into the user interface device 55manually.

For example, the user interface device 55A (one of the plurality of userinterface devices 55) is associated with the bed 51A (one of theplurality of beds 51), an auxiliary device 52A (one of the plurality ofauxiliary devices 52), and a measurement device 53A (one of theplurality of measurement devices 53). The user interface device 55B, forexample, is associated with the bed 51B, an auxiliary device 52B, and ameasurement device 53B. The user interface device 55C, for example, isassociated with the bed 51C, an auxiliary device 52C, and a measurementdevice 53C.

The bed moving part information 51 i, the user behavior information 52i, and the measurement information 53 i, described above, are suppliedto the acquisition unit 61I via the user interface device 55 as the userinterface device information 55 i.

In this example, at least a part of the user interface deviceinformation 55 i is supplied to a second display 62. The second display62 is a display of a mobile terminal, for example. A caregiver or thelike, for example, uses the second display 62. The caregiver or the likeprovides the respective users of the plurality of beds with nursing careor medical care. For example, each of a plurality of caregivers or thelike owns one second display 62.

At least one of the first display 61 and the second display 62 includesa display device (a liquid crystal display device, an EL display device,or the like, for example), for example. The size (the length of thediagonal of the screen, for example) of the first display 61 is greaterthan the size (the length of the diagonal of the screen, for example) ofthe second display 62. The acquisition unit 61I may be provided in acasing in which the first display 61 is provided.

Meanwhile, the plurality of caregivers or the like share the firstdisplay 61. The first display 61 is provided in a nurse station or thelike, for example. The first display 61 is a display of a master stationdevice, for example. The first display 61 is provided in a differentposition to the plurality of user interface devices 55. The firstdisplay 61 is provided in a location (a remote location) apart from theplurality of user interface devices 55. From the display on the firstdisplay 61 provided in a remote location, the caregivers or the like canascertain the states of the beds 51 connected to the plurality of userinterface devices 55 or the states of the users of the beds 51.

The first display 61 displays a plurality of images 61G on a singlescreen 61D on the basis of the plurality of user interface deviceinformation 55 i acquired by the acquisition unit 61I. The plurality ofimages 61G correspond respectively to the plurality of user interfacedevices 55.

The single screen 61D displays the plurality of images 61G correspondingrespectively to the plurality of user interface devices 55 side by side.The caregivers or the like can thus ascertain the states of therespective users of the plurality of beds 51 efficiently and in aneasily understandable manner. As a result, a bed system having improvedusability can be provided.

The plurality of beds 51 are provided in a hospital, a care facility, orthe like, for example. The user interface devices 55 are providedrespectively on the plurality of beds 51. One user interface device 55can provide the caregiver or the like with information relating to thestate of the bed 51 to which the user interface device 55 is connectedand the state of the user of the bed 51. Meanwhile, in a nurse stationlocated away from the bed 51, it is necessary to ascertain the states ofthe plurality of beds 51 and the plurality of users as a whole. Bydisplaying the plurality of images 61G on the single screen 61D, theoverall situation can be ascertained. As a result, high-prioritymeasures can be implemented efficiently.

For example, the plurality of user interface device information 55 iacquired from the plurality of user interface devices 55 is displayed atthe same time on the single screen 61D of the first display 61. Theplurality of images 61G are displayed collectively on the single screen61D. As a result, the information can be ascertained more easily than ina case where, for example, the plurality of user interface devices 55are accessed individually from the nurse station and information isacquired from each of the plurality of user interface devices 55.

According to an embodiment, information exchange (communication) isperformed rapidly between a plurality of caregivers and the like, forexample. Communication delays are suppressed. The productivity of thecaregiver or the like improves. Risks to the users can be identifiedquickly.

As described above, one set of the plurality of user interface deviceinformation 55 i includes state information. The state informationincludes at least one of the bed state information relating to the stateof one bed 51 among the plurality of beds 51 and the user stateinformation relating to the state of the user of the one bed 51 amongthe plurality of beds 51. The bed state information includes, forexample, the bed moving part information relating to at least one of theheight and the angle of the one bed 51 among the plurality of beds 51.The user state information includes at least one of the vital signsinformation relating to the user and the user behavior informationrelating to the user. The vital signs information includes informationrelating to at least one of the blood pressure, the blood oxygensaturation, the blood glucose level, the heart rate, the pulse rate, therespiration rate, the weight, and the body temperature of the user. Theuser behavior information includes information relating to at least oneof bed departure, sleeping, waking up, sitting up, and sitting on theedge of the bed in relation to the user.

One image among the plurality of images 61G includes a state display (apictogram, a color, or the like, to be described below) corresponding tothe state information described above. As will be described below, whenthe state information is abnormal, the first display 61 displays awarning display on the one image among the plurality of images 61G.

In an embodiment, as will be described below, the plurality of stateinformation (the bed moving part information 51 i, the user behaviorinformation 52 i, the measurement information 53 i, and so on) includedin the user interface device information 55 i is displayed as a singlecombination. As a result, the state information relating to the statesof the plurality of beds 51 and the plurality of users can be displayedclearly on the single screen 61D. By employing a display of combinedinformation, risks can be identified easily and efficiently. Forexample, signs indicating risk to a user (an injury, a deterioration ofthe medical condition, and so on) can easily be ascertained from thestates of the plurality of beds 51 and the states of the plurality ofusers at an appropriate timing.

Hence, according to an embodiment, efficiently ascertaining the statesof the plurality of beds 51 (states of devices) and the states of theplurality of users in a remote location can be achieved more easily. Asa result, an improvement in usability can be achieved. For example, thequality of medical or nursing care can be improved.

A processing device such as a computer, for example, generates datarelating to the screen 61D and the plurality of images 61G displayed onthe first display 61. The processing device may be provided in theacquisition unit 61I or the first display 61, for example. Theprocessing device may be provided in the server 65 or the like, forexample.

Examples of displays displayed on the first display 61 will be describedbelow.

FIG. 2 is a pattern diagram showing an example of a bed system accordingto an embodiment.

FIG. 2 shows an example of the screen 61D of the first display 61. Asshown in FIG. 2, the single screen 61D displays the plurality of images61G side by side. In this example, a message is displayed in a messageregion 61M. For example, the message is a communication state error orthe like, for example.

One of the plurality of images 61G includes a first partial region R1, asecond partial region R2, and a third partial region R3. In thisexample, an outer edge partial region R4 is further provided. The outeredge partial region R4 is provided on the periphery of the first partialregion R1, the second partial region R2, and the third partial regionR3. The plurality of images 61G are displayed within a background regionR5 of the single screen 61D. The outer edge partial region R4 clarifiesa boundary between the background region R5 and the image 61G.

For example, the background region R5 is white, for example. The outeredge partial region R4 is a pale color (pale blue or the like), forexample.

At least a part of the second partial region R2 is positioned betweenthe first partial region R1 and the third partial region R3. Forexample, the third partial region R3 is positioned around the firstpartial region R1 and the second partial region R2. The third partialregion R3 is frame-shaped, for example.

One of the plurality of images 61G corresponds to one of the pluralityof user interface devices 55 (a subject user interface device 55). Inother words, one of the plurality of images 61G corresponds to one setof the plurality of user interface device information 55 i. The subjectuser interface device 55 corresponds to one bed 51 (the subject bed 51)and one user (the subject user).

Accordingly, one of the plurality of images 61G corresponds to thesubject bed 51 and the subject user. One of the plurality of images 61Gwill be described below.

The first display 61 displays a pictogram in the first partial regionR1, for example. The first display 61 displays the identificationinformation I1 specifying the user in at least a part of the secondpartial region R2. The first display 61 displays a warning display 30Ain the third partial region R3. Examples of these displays will bedescribed below.

A pictogram is displayed in the first partial region R1. The pictogramincludes a state display corresponding to the state information (atleast one of the bed state information and the user state information).The pictogram includes the bed moving part information 51 i, forexample. As described above, the bed moving part information 51 iincludes information relating to at least one of the height and theangle of one of the plurality of beds 51. For example, the pictogramincludes a pattern (including characters) corresponding to the height ofthe subject bed 51. For example, the pictogram includes a pattern(including characters) corresponding to the angle of the subject bed 51.The pictogram includes the user state information (for example, thevital signs information and the user behavior information). Thepictogram forms at least a part of the state information.

The identification information I1 is displayed in the second partialregion R2. In this example, vital signs information I2 is also displayedin the second partial region R2. The identification information I1specifies the user (the subject user) of one bed (the subject bed 51)among the plurality of beds 51. The identification information I1includes the name of the subject user, for example. The vital signsinformation I2 includes information relating to the vital signs of thesubject user. The vital signs information I2 includes informationrelating to at least one of the blood pressure, the blood oxygensaturation, the blood glucose level, the heart rate, the pulse rate, therespiration rate, the weight, and the body temperature of the subjectuser.

For example, the identification information I1 includes characterinformation (the characters of the name and so on). The vital signsinformation I2 is displayed according to color. More specifically, inthe second partial region R2, the color of the region, excluding theidentification information I1, is modified on the basis of the vitalsigns of the subject user. Thus, the vital signs information I2 may bedisplayed according to the color on the periphery of the identificationinformation I1. As a result, the condition (the vital signs) of thesubject user can be recognized more easily while ensuring that theidentification information I1 remains easy to see. An example of displayof the vital signs information I2 according to color will be describedbelow.

Hence, the first display 61 displays the identification information I1and the vital signs information I2 in the second partial region R2. Thevital signs information I2 forms at least a part of the stateinformation.

Meanwhile, a warning display 30A is displayed in the third partialregion R3. The warning display 30A is displayed when a specificcondition is satisfied. When the state information is abnormal, thewarning display 30A is displayed in the third partial region R3 of oneof the plurality of images 61G. For example, the first display 61displays the warning display 30A when at least one of the bed-departurestate of the subject user, the waking-up state of the subject user, thesitting-up state of the subject user, the sitting-on-the-edge-of-the-bedstate of the subject user, the heart rate of the subject user, and therespiration rate of the subject user is abnormal. The first display 61may also display the warning display 30A in the third partial region R3when the bed state information is abnormal. As described above, thesubject items of the warning display 30A include bed departure, wakingup, sitting up, sitting on the edge of the bed, heart rate, respirationrate, and so on. These subject items may be acquired automaticallyrather than manually, for example. These subject items are acquiredcontinuously without human intervention, for example. Therefore, when anabnormal state occurs among the subject items, it may be difficult tonotice the abnormal state. By displaying the warning display 30A inrelation to these subject items, more appropriate services can beprovided.

A reference (a threshold) for determining whether or not an abnormalstate has occurred may be determined in accordance with the state (thecondition and so on) of the subject user, for example. For example, whenthe bed 51 or the auxiliary device 52 of a user who finds walkingdifficult detects that the user is out of bed, a serious accident suchas the user falling from the bed 51 may occur. In this case, a rapidresponse is necessary. In such cases, the warning display 30A isdisplayed after detecting the bed departure state. In contrast, when beddeparture is detected in relation to a user who finds walking easy, thepossibility of a serious accident is comparatively low. In such cases,the warning display 30A need not be displayed even after detecting thebed departure state.

The reference for determining whether or not an abnormal state hasoccurred may be determined on the basis of a combination of the state ofthe subject user and the state of the bed 51 or the like, for example.When the bed departure state is detected in relation to a user who findswalking difficult and whose bed 51 is high, the user may fall from thehigh bed 51. In such cases, the warning display 30A is displayed.

The auxiliary device 52 (or the bed 51) or the like detects informationrelating to heart rate and respiration rate continuously, for example.As a result, information relating to the steady heart rate andrespiration rate of the subject user accumulates. When a dramaticvariation from the steady heart rate and respiration rate is observed,the warning display 30A is displayed. When the degree of variation isintermediate, a notification display 30N to be described below may bedisplayed.

In this example, the notification display 30N is displayed in the thirdpartial region R3. For example, the first display 61 may also displaythe notification display 30N when at least one of the heart rate of thesubject user and the respiration rate of the subject user varies so asto exceed a reference.

For example, the heart rate of the subject user and the respiration rateof the subject user are acquired from the subject bed 51 (one of theplurality of beds) or the auxiliary device 52 of the subject bed 51 (oneof the plurality of beds). As described above, the auxiliary device 52may be considered as a part of the bed 51.

The heart rate of the subject user and the respiration rate of thesubject user are detected continuously. When the continuously detectedheart rate or respiration rate varies so as to exceed a reference (whenan event occurs), the condition of the user may have deteriorated. Bydisplaying the notification display 30N when such evidence ofdeterioration is found, appropriate countermeasures can be takenrapidly.

The reference used to determine whether or not to display thenotification display 30N is determined in accordance with the state ofthe subject user, for example. A looser reference than the referenceused to determine whether or not the display the warning display 30A,for example, is employed as the reference (the threshold) fordetermining whether or not to display the notification display 30N. Forexample, a nurse or the like prioritizes care of a user for whom thewarning display 30A is displayed over care of a user for whom thenotification display 30N is displayed.

By displaying the warning display 30A, the nurse or the like can easilyidentify the user (the care-receiver) having the highest priority.Further, by displaying the notification display 30N, the nurse or thelike can easily identify the user (the care-receiver) having the secondhighest priority. As a result, the quality of medical or nursing carecan be improved, for example.

In this example, a window region 61H is provided on the single screen61D. At least a part of the information relating to one of the pluralityof users, for example, is displayed in the window region 61H. In thisexample, information relating to the body temperature, the bloodpressure (the systolic blood pressure and the diastolic blood pressure),the heart rate, the pulse rate, the respiration rate, the SpO₂, and theblood glucose is displayed. By clicking (touching) one of the pluralityof images 61G, for example, the information relating to the subject usercorresponding to that image 61G is displayed in the window region 61H.

Hence, when one of the plurality of images 61G receives input, the firstdisplay 61 may display the information corresponding to that image 61G.This information forms at least a part of the information relating tothe subject user corresponding to the image 61G, for example. Theinformation corresponding to this one image among the plurality ofimages 61G may be displayed in a part of the single screen 61D, forexample (in the window region 61H, for example). By providing the windowregion 61H on the same screen 61D, the warning display 30A can bepresented to a nurse or the like even while the caregiver or the like isviewing the information displayed in the window region 61H, for example.As a result, cases in which the warning display 30A and so on areoverlooked can be suppressed.

In an embodiment, the window region 61H may be provided on a separatescreen. For example, when one of the plurality of images 61G receivesinput, the single screen 61D may shift to a different screen. In thiscase, a different screen can be used, and therefore information relatingto the subject user can be displayed in detail.

Several examples of the images 61G will be described below.

FIGS. 3(a) to 3(d) are pattern diagrams showing examples of imagesdisplayed in a bed system according to an embodiment.

As shown in FIG. 3(a), the single image 61G is provided with the firstpartial region R1, the second partial region R2, and the third partialregion R3. In this example, an outer edge partial region R4 is furtherprovided. The ward number 13 (in this example, “2221”) of the subjectuser may be displayed in the outer edge partial region R4.

As described above, the pictogram PG is displayed in the first partialregion R1. The identification information I1 and the vital signsinformation I2 are displayed in the second partial region R2. In thisexample, the number 14 (in this example, “01”) of the subject userwithin the ward is displayed in a part of the second partial region R2.

FIG. 3(b) shows an example of the first partial region R1. FIG. 3(c)shows an example of the second partial region R2. FIG. 3(d) shows anexample of the third partial region R3.

As shown in FIG. 3(b), the first partial region R1 has a verticaldirection length L1 and a lateral direction length W1. As shown in FIG.3(c), the second partial region R2 has a vertical direction length L2and a lateral direction length W2. As shown in FIG. 3(d), the thirdpartial region R3 has a vertical direction length L3 and a lateraldirection length W3.

In an embodiment, the length L3 is greater than the length L1. Thelength L3 is greater than the length L2. The length W3 is greater thanthe length W1. The length W3 is greater than the length W2.

Hence, the vertical direction length L3 and the lateral direction lengthW3 of the third partial region R3 are long. Accordingly, the outer shapeof the third partial region R3 is larger than the outer shape of thefirst partial region R1 and the outer shape of the second partial regionR2. Thus, for example, the warning display 30A or a notification display30N displayed in the third partial region R3 is clearly visible.

A nurse or the like can identify necessary warnings and notifications inan easily understandable manner.

Meanwhile, for example, the surface area of the second partial region R2is greater than the surface area of the first partial region R1. Forexample, the surface area of the vital signs information I2 displayed inthe second partial region R2 is greater than the surface area of thepictogram PG displayed in the first partial region R1. The vital signsinformation I2 often has a higher priority than the information acquiredfrom the pictogram PG. With this surface area relationship, a nurse orthe like can identify high-priority information (the vital signsinformation I2) preferentially.

Examples of displays displayed in the third partial region R3 will bedescribed below.

FIGS. 4(a) to 4(c) are pattern diagrams showing examples of imagesdisplayed in a bed system according to an embodiment.

FIG. 4(a) shows a state in which no information is displayed in thethird partial region R3. FIG. 4(b) shows a state in which thenotification display 30N is displayed in the third partial region R3.FIG. 4(c) shows a state in which the warning display 30A is displayed inthe third partial region R3.

As shown in FIG. 4(a), when no information is displayed in the thirdpartial region R3, the state of the third partial region R3 is identicalto the state of at least a part of the second partial region R2. Forexample, the color of the third partial region R3 is the same as thecolor of the vital signs information I2 in the second partial region R2.

The recognizability of the notification display 30N shown in FIG. 4(b)is higher than the recognizability of the vital signs information I2 inthe second partial region R2, for example. The color of the notificationdisplay 30N is dark red, for example. The vital signs information I2, onthe other hand, is displayed in a pale color (pale pink, pale yellow,pale green, pale blue, or the like, for example). The notificationdisplay 30N can thus be recognized more easily.

An attention-alerting property (the recognizability) of the warningdisplay 30A shown in FIG. 4(c) is higher than the attention-alertingproperty (the recognizability) of the notification display 30N, forexample. For example, the warning display 30A may include flashing. Thenotification display 30N, on the other hand, does not flash. The warningdisplay 30A includes a distinctively shaped pattern 30Aa, for example.The distinctively shaped pattern 30Aa is not provided in thenotification display 30N. In this example, the distinctively shapedpattern 30Aa is displayed in the shape of a “bell”. Due to thedistinctively shaped pattern 30Aa, the surface area of the warningdisplay 30A is larger than the surface area of the notification display30N. Thus, the warning display 30A has at least one of a larger surfacearea than the notification display 30N and a different pattern to thepattern included in the notification display 30N, for example. As aresult, the attention-alerting property of the warning display 30A ishigher than the attention-alerting property of the notification display30N.

The color of the warning display 30A may be different to the color ofthe notification display 30N. For example, the warning display 30A isdark red. The notification display 30N may have a red color that ispaler than the color of the warning display 30A. For example, the chromaof the warning display 30A may be higher than the chroma of thenotification display 30N.

As shown in FIG. 4(c), the region displaying the distinctively shapedpattern 30Aa forming a part of the warning display 30A is consideredpart of the third partial region R3. As shown in FIGS. 4(a) and 4(b),when the warning display 30A is not displayed, this part of the thirdpartial region R3 is identical to the state of at least a part of thesecond partial region R2. For example, the color of this part of thethird partial region R3 is the same as the color of the vital signsinformation I2 in the second partial region R2.

Examples of displays displayed in the second partial region R2 will bedescribed below.

FIGS. 5(a) to 5(c) are pattern diagrams showing examples of imagesdisplayed in a bed system according to an embodiment.

These figures correspond to the plurality of information displayed inthe second partial region R2. As described above, the identificationinformation I1 (character information such as a name, for example) andthe vital signs information I2 (color information, for example) aredisplayed in the second partial region R2. For example, at least a partof the vital signs information I2 is between the identificationinformation I1 and the third partial region R3 (the warning display 30Aand the notification display 30N).

In this example, the vital signs information I2 is displayed accordingto color. In this example, the vital signs information I2 is displayedusing three colors (a first color C1, a second color C2, and a thirdcolor C3). FIGS. 5(a) to 5(c) correspond respectively to the threecolors.

The first color C1, shown in FIG. 5(a), corresponds to “normal”, forexample. The second color C2, shown in FIG. 5(b), corresponds to“caution”. The third color C3, shown in FIG. 5(c), corresponds to“warning”.

For example, the chroma of the third color C3 is higher than the chromaof the second color C2. The chroma of the second color C2 is higher thanthe chroma of the first color C1. The third color C3 is darker than thesecond color C2. The second color C2 is darker than the first color C1.As a result, for example, the third color C3 is more easily recognizablethan the other two colors. As a result, the second color C2 is moreeasily recognizable than the first color C1.

For example, the third color C3 is a color close to red. The first colorC1 is a color distant from red. For example, an absolute value of adifference between a hue of the third color C3 and a hue of red issmaller than an absolute value of a difference between a hue of thesecond color C2 and the hue of red. For example, the absolute value ofthe difference between the hue of the second color C2 and the hue of redis smaller than an absolute value of a difference between a hue of thefirst color C1 and the hue of red.

For example, the third color C3 is pale red. The second color C2 is paleyellow. The third color C3 is substantially white.

When the warning display 30A (or the notification display 30N) displayedin the third partial region R3 is a red-based color, the color of thewarning display 30A (or the notification display 30N) is darker than thecolor (pale red, for example) of the third color C3.

For example, the chroma of the notification display 30N is higher thanthe chroma of the display of the vital signs information I2. The chromaof the notification display 30N is higher than the chroma of the firstcolor C1, higher than the chroma of the second color C2, and higher thanthe chroma of the third color C3. As a result, the attention-drawingability of the notification display 30N can be enhanced.

For example, an absolute value of a difference between a hue of thenotification display 30N and the hue of red is smaller than an absolutevalue of a difference between a hue of the display of the vital signsinformation I2 and the hue of red. For example, the absolute value ofthe difference between the hue of the notification display 30N and thehue of red is smaller than the absolute value of the difference betweenthe hue of the first color C1 and the hue of red. The absolute value ofthe difference between the hue of the notification display 30N and thehue of red is smaller than the absolute value of the difference betweenthe hue of the second color C2 and the hue of red. The absolute value ofthe difference between the hue of the notification display 30N and thehue of red is smaller than the absolute value of the difference betweenthe hue of the third color C3 and the hue of red. As a result, theattention-drawing ability of the notification display 30N can beenhanced.

For example, the chroma of the warning display 30A is higher than thechroma of the display of the vital signs information I2. For example,the chroma of the warning display 30A is higher than the chroma of thefirst color C1, higher than the chroma of the second color C2, andhigher than the chroma of the third color C3. As a result, theattention-drawing ability of the warning display 30A can be enhanced.

For example, an absolute value of a difference between a hue of thewarning display 30A and the hue of red is smaller than the absolutevalue of the difference between the hue of the display of the vitalsigns information I2 and the hue of red. For example, the absolute valueof the difference between the hue of the warning display 30A and the hueof red is smaller than the absolute value of the difference between thehue of the first color C1 and the hue of red. The absolute value of thedifference between the hue of the warning display 30A and the hue of redis smaller than the absolute value of the difference between the hue ofthe second color C2 and the hue of red. The absolute value of thedifference between the hue of the warning display 30A and the hue of redis smaller than the absolute value of the difference between the hue ofthe third color C3 and the hue of red. As a result, theattention-drawing ability of the warning display 30A can be enhanced.

For example, the vital signs information I2 has a pale color. The vitalsigns information I2 is displayed close to the identificationinformation I1. When the vital signs information I2 has a dark color,the recognizability of the identification information I1 deteriorates.By displaying the vital signs information I2 in a pale color, a nurse orthe like can identify the desired vital signs information I2 in aneasily understandable manner while the identification information I1remain highly recognizable.

For example, when the warning display 30A or the notification display30N is displayed, the identification information I1 is preferablyclearly visible. Thus, the caregiver or the like can identify the userin relation to whom a warning or a notification has been issued in aneasily understandable manner. The identification information I1 ispreferably black (a dark color), for example. Thus, high recognizabilityis acquired in relation to the identification information I1.

The display of the vital signs information I2, meanwhile, is displayedaccording to color. As a result, the caregiver or the like can recognizethe medical condition of the subject user intuitively, in an easilyunderstandable manner. The color is comparatively pale. Thus,deterioration of the recognizability of the identification informationI1 can be suppressed.

The warning display 30A (or the notification display 30N) needs to havea superior attention-drawing ability. By making the color of the displayof the vital signs information I2 comparatively pale, theattention-drawing ability of the warning display 30A (or thenotification display 30N) can be enhanced.

As described above, at least a part of the pale-colored vital signsinformation I2 is between the identification information I1 and thethird partial region R3 (the warning display 30A and the notificationdisplay 30N). Thus, a situation in which the identification informationI1 becomes difficult to see when the warning display 30A or thenotification display 30N is displayed can be suppressed.

As described above, the third partial region R3 in which the warningdisplay 30A or the notification display 30N is displayed has a largerouter shape than the first partial region R1 and the second partialregion R2. As a result, a superior attention-drawing ability is acquiredin relation to the warning display 30A or the notification display 30N.By making the color of the vital signs information I2 pale, theidentification information I1 remains clearly visible even when thewarning display 30A or the notification display 30N is displayed.

By combining the second partial region R2 and the third partial regionR3 in this manner, the warning display 30A or the notification display30N can be recognized in an easily understandable manner. Further, sincethe vital signs information I2 is displayed in the second partial regionR2 according to color, the caregiver or the like can recognize themedical condition of the subject user intuitively, in an easilyunderstandable manner.

In an embodiment, as described above, the pictogram PG is displayed inthe first partial region R1. Hence, from the single image 61G, thecaregiver or the like can easily recognize the overall situation,including the state of the subject bed 51 (the bed moving partinformation 51 i) and the state of the subject user (the user behaviorinformation 52 i) in an easily understandable manner.

The real-time property of the warning display 30A or the notificationdisplay 30N is superior to that of the vital signs information I2. Abold color is used for the warning display 30A or the notificationdisplay 30N having a superior real-time property. As a result, thewarning display 30A or the notification display 30N can be recognizedrapidly.

Several examples of the pictogram PG displayed in the first partialregion R1 will be described below.

FIGS. 6(a) and 6(b) are pattern diagrams showing examples of imagesdisplayed in a bed system according to an embodiment.

These figures show examples of the pictogram PG. In these examples, theinformation (the bed moving part information 51 i) relating to thesubject bed 51 is displayed by a bed moving part display 51 iD.

As shown in FIG. 6(a), in this example, the height of the subject bed 51is displayed using a height display pattern 11. In this example, theheight display pattern 11 has a downward-pointing triangular shape. Whenthe height display pattern 11 is displayed, the height of the bed is low(at the lowest level, for example).

As shown in FIG. 6(b), the height display pattern 11 is not displayed,for example. This state indicates that the height of the bed is high(above floor level, for example), for example.

Thus, the presence or absence of a display pattern (the height displaypattern 11 or the like) can be used as the bed moving part display 51iD.

FIGS. 7(a) to 7(j) are pattern diagrams showing examples of imagesdisplayed in a bed system according to an embodiment.

These figures show examples of the pictogram PG. In these examples, anangle display pattern 12 and angle display characters 13 are used as thebed moving part display 51 iD of the pictogram PG.

In the examples shown in FIGS. 7(a), 7(c), 7(e), 7(g), and 7(i), theangle display pattern 12 extends in a lateral direction (a horizontaldirection). This angle display pattern 12 indicates that the angle ofthe bed 51 (the angle of the back section 70 a, for example) is small (ahorizontal state in which the angle is 0 degrees, for example). FIGS.7(a), 7(e), and 7(i) are used when the subject user is out of the bed 51(i.e. in a bed departure state), for example. FIGS. 7(c) and 7(g) areused when the subject user is lying flat on the bed 51, for example.

In the examples shown in FIGS. 7(b), 7(d), 7(f), 7(h), and 7(j), theangle display pattern 12 is inclined. This angle display pattern 12indicates that the angle of the bed 51 is large (30 degrees or the like,for example). In these examples, the angle display characters 13indicating the approximate angle of incline are also displayed. FIGS.7(b), 7(f), and 7(j) are used when the subject user is out of the bed 51(i.e. in a bed departure state), for example. FIGS. 7(d) and 7(h) areused when the subject user is lying flat on the bed 51, for example. Itis acceptable to display at least one of the angle display pattern 12and the angle display characters 13.

The color of the angle display pattern 12 in FIGS. 7(a) to 7(d) isdifferent to the color of the angle display pattern 12 in FIGS. 7(e) to7(h). The color of the angle display pattern 12 in FIGS. 7(a) to 7(d) isdifferent to the color of the angle display pattern 12 in FIGS. 7(i) and7(j). The color of the angle display pattern 12 in FIGS. 7(e) to 7(h) isdifferent to the color of the angle display pattern 12 in FIGS. 7(i) and7(j). As will be described below, these colors may be determined inaccordance with the state of the subject user, such as waking up,sleeping, and bed departure, for example.

FIGS. 8(a) to 8(1) are pattern diagrams showing examples of imagesdisplayed in a bed system according to an embodiment.

These figures show examples of the pictogram PG. In these examples, theheight display pattern 11, the angle display pattern 12, the angledisplay characters 13, and a user behavior display 14 are displayed asthe pictogram PG. The user behavior display 14 corresponds to the userbehavior information 52 i. As described above, the user behaviorinformation 52 i includes information relating to the user behaviorstate, including at least one of bed departure, sleeping, waking up,sitting up, and sitting on the edge of the bed, in relation to the userof the bed 51. In this example, the user behavior state is classified asone of three states, namely sleeping, waking up, and bed departure.Three display patterns are used as the user behavior display 14.

In the examples shown in FIGS. 8(a), 8(d), 8(g), and 8(j), the userbehavior display 14 corresponding to sleeping is displayed. In theexamples shown in FIGS. 8(b), 8(e), 8(h), and 8(k), the user behaviordisplay 14 corresponding to waking up is displayed. In the examplesshown in FIGS. 8(c), 8(f), 8(i), and 8(1), the user behavior display 14corresponding to bed departure is displayed.

As illustrated by these figures, the single pictogram PG includes a setof the height display pattern 11, the angle display pattern 12, theangle display characters 13, and the user behavior display 14.

The color (a fourth color C4) of the user behavior display 14corresponding to sleeping may differ from the color (a fifth color C5)of the user behavior display 14 corresponding to waking up. The fourthcolor may differ from the color (a sixth color C6) of the user behaviordisplay 14 corresponding to bed departure. The fifth color C6 may differfrom the sixth color C6.

For example, when the user is awake on the bed 51, the possibility of anaccident or the like may be higher than when the user is asleep on thebed 51. Therefore, the attention-drawing ability of the color (the fifthcolor C5) used when the user is awake on the bed 51 is preferably higherthan the attention-drawing ability of the color (the fourth color C4)used when the user is asleep on the bed 51.

For example, the chroma of the fifth color C5 is higher than the chromaof the fourth color C4. For example, the absolute value of thedifference between the hue of the fifth color C5 and the hue of red issmaller than the absolute value of the difference between the hue of thefourth color C4 and the hue of red. For example, the fourth color C4 ispale blue and the fifth color C5 is pale yellow.

When the user is out of bed, meanwhile, it is impossible to ascertainanother state of the user from the information acquired from the bed 51(or the auxiliary device 52). Hence, the color (the sixth color C6) usedwhen the user is out of bed may be an unobtrusive color. For example,the chroma of the sixth color C6 is lower than the chroma of the fourthcolor C4. For example, the sixth color C6 is gray.

FIGS. 9(a) to 9(d) are pattern diagrams showing examples of imagesdisplayed in a bed system according to an embodiment.

These figures correspond to cases in which the pictogram PG displays thebed moving part display 51 iD (information relating to the subject bed51) but does not display the user behavior display 14 (sleeping, wakingup, bed departure, and so on, for example). The height display pattern11, the angle display pattern 12, and the angle display characters 13are displayed as the bed moving part display 51 iD of the pictogram PG.

FIGS. 10(a) to 10(c) are pattern diagrams showing examples of imagesdisplayed in a bed system according to an embodiment.

These figures correspond to cases in which the pictogram PG does notdisplay the bed moving part display 51 iD but does display the userbehavior display 14 (sleeping, waking up, bed departure, and so on, forexample).

Thus, various modifications can be applied to the pictogram PG.

For example, in an embodiment, information such as the state of the bed51, the behavior state of the user of the bed 51, and the medicalcondition of the user, for example, is presented in a location (a remotelocation) away from the bed 51. The state of the bed 51 includes anoperation state, a setting state, an error state, and so on of the bed51. The state of the bed 51 may also include the state of the userinterface device (an operation state, a setting state, an error state,and so on). The behavior state of the user includes at least one of beddeparture, sleeping, waking up (lying flat on the bed), sitting up, andsitting on the edge of the bed, for example. The medical condition ofthe user includes normal, poor, critical, and so on, for example. Themedical condition of the user includes at least one of heart rate,respiration rate, blood pressure, blood oxygen saturation, blood glucoselevel, and body temperature, for example. On the basis of the state ofthe bed 51, the behavior state of the user of the bed 51, the medicalcondition of the user, and so on, a doctor, a nurse, or the like, forexample, implements treatment, issues instructions, confirms risk, andso on. By presenting the state of the bed 51, the behavior state of theuser, the medical condition of the user, and so on in relation to theplurality of beds 51 on a single screen in a remote location, a nurse orthe like can recognize the information quickly and efficiently.

In an embodiment, information having a superior real-time property (thewarning display 30A or the notification display 30N) is displayed in alarge size (vertical direction length and lateral direction length) andin a bold color, for example. Meanwhile, high-priority information (thevital signs information I2 and so on, for example) is displayed over alarge surface area in a pale color or the like. Further, informationrelating to the state of the bed 51 and the state of the user (the bedmoving part information 51 i and the user behavior information 52 i, forexample) is combined and displayed using the pictogram PG.

Hence, when a plurality of information is displayed on the single screen61D in relation to the plurality of beds 51, an improvement in therecognizability (including the attention-drawing ability) of theplurality of information can be expected.

The user interface device 55 is provided for each of the plurality ofbeds 51. As a result, information relating to the plurality of beds 51and the plurality of users can be collected from each bed 51. Theinformation acquired by the plurality of user interface devices 55 issupplied to the acquisition unit 61I via a server, for example.

According to an embodiment, a nurse or the like, for example, cancollect information more quickly. Risks can be ascertained early,leading to an improvement in the quality of medical care or nursingcare.

The bed system 110 according to an embodiment may further include theplurality of beds 51. The plurality of user interface devices 55 areconnected respectively to the plurality of beds 51. The bed system 110may further include the auxiliary device 52. The bed system 110 mayfurther include a second display 62. The bed system 110 may furtherinclude the server 65. The bed system 110 may further include anelectronic medical record storage unit 66.

As described above, one (each) of the plurality of bed devices 50includes the bed 51 and the user interface device 55. The user interfacedevice 55 is connected to the bed 51. The user interface device 55 maybe provided as a separate component to the bed 51, for example. Forexample, the user interface device 55 may be provided separately to thebed 51 (or components (a side rail, a frame, and so on) included in thebed 51). By providing the user interface device 55 as a separatecomponent to the bed 51, the combination of the bed 51 and the userinterface device 55 can be modified, for example. As a result, varioussituations can be dealt with easily, leading to a further improvement inusability.

An example of the first input/output device 60 will now be described.

FIG. 11 is a pattern diagram showing an example of a part of a bedsystem according to an embodiment.

FIG. 11 is a block diagram of the first input/output device 60.

The controller 60 g includes an electronic circuit (a CPU: CentralProcessing Unit or the like, for example), for example. The controller60 g executes processing based on the program, for example. For example,the controller 60 g compares the measurement values with the set valuesand so on, for example. The controller 60 g then causes at least one ofthe display 60 c and the output device 60 e to issue a report inaccordance with the comparison result.

FIG. 12 is a flowchart showing an example of an operation performed in abed system according to an embodiment.

FIG. 12 shows an operation performed by a controller (the controller 60g, for example) according to an embodiment. For example, the controller60 g acquires the user interface device information 55 i (step S110).The user interface device information 55 i includes the measurementvalues of the plurality of items in the plurality of bed devices 50. Thecontroller 60 g determines whether or not the measurement values exceedset ranges (a range determined by the first set value, a rangedetermined by the first set value, and so on). When a measurement valueexceeds a set range, the controller 60 g causes another device (thedisplay 60 c, the output device 60 e, or the like) to issue a report(step S130). The processing then returns to step S110. When themeasurement values do not exceed the set ranges, on the other hand, theprocessing returns to step S110. By implementing this processing,reports are issued appropriately.
